Fluoride Release of New Bioactive Orthodontic Adhesive with Color Change and Fluorescent Property

Objective: This study aimed to assess the effect of adding fluorescent dyes & color change dyes in different concentration to bioactive orthodontic adhesive on fluoride release. Material and Methods: We used Bioactive BEAUTIFIL Injectable XSL (S-PRG), from (Giomer, Shofu, Japan) mixed with color change dye, Black changing to Colorless, (Atlanta chemical engineering, USA). 0.02%, 0.2% and 2% of weight concentrations were tested and with fluorescence dye (Strontium aluminate), and White Glow in the Dark Powder (Techno Glow Inc., USA), using in 5%, 10% and 15% of weight concentrations. For fluoride release, 40 samples prepared and divided into 4 groups with 10 samples as following: Group 1: BEAUTIFIL Injectable XSL Adhesive (control group), Group 2: BEAUTIFIL Injectable XSL with 0.02% color change material and 5% fluorescence material. Group3: BEAUTIFIL Injectable XSL with 0.2% color change material and 10% fluorescence material. Group 4: BEAUTIFIL Injectable XSL with 2% fluorescence material and 15% fluorescence material. fluoride Ion Selective Electrode. Eutech ION 2700.) Thermo Fisher scientific inc. Singapore) used to measure the release of fluoride ion. Results: The use of dyes with bioactive adhesive showed statistically significant differences. There was a decrease in fluoride ion with increase dye concentration. Conclusion: Acceptable fluoride ion release within bioactive adhesive with color change and fluorescence properties was obtained but with increase concentration of dyes the ion release decreased.
